API RP 550 P1 S5-1965 Manual on Installation of Refinery Instruments and Control Systems - Part I - Process Instrumentation and Control Section 5 - Automatic controllers (Second Edition)
FOREWORD This recommended practice is based on the accumulated knowledge and experience of engineers in the petroleum industry. Its purpose is to aid in the installation of the more generally used measuring@ control@ and analytical instruments; transmission systems; and related accessories in order to achieve safe@ continuous@ accurate@ and efficient operation with minimum maintenance. Although the information contained herein has been prepared primarily for petroleum refineries@ much of it is applicable without change in chemical plants@ gasoline plants@ and similar installations. Successful instrumentation depends upon a workable arrangement that incorporates the simplest system and devices that will satisfy specified requirements. Sufficient schedules@ drawings. sketches@ and other data should be provided to enable the constructor to install the equipment in the desired manner. The various industry codes and standards@ and laws and rulings of regulating bodies should be followed where applicable. The information contained in this publication does not constitute@ and should not be construed to be@ a code of rules or regulations. Furthermore@ it does not grant the right@ by implication or otherwise@ for manufacture@ sale@ or use in connection with any method@ apparatus@ or product covered by letters patent; nor does it ensure anyone against liability for infringement of letters patent. For maximum plant personnel safety@ transmission sys'tems are employed to eliminate the piping of hydrocarbons@ acids@ and other hazardous or noxius materials to instruments in control rooms. Proper installation is essential in order to utilize the full capabilities which are built into the instrument or transmission system. In the installation of an instrument@ the various components must be accessible for efficient maintenance and certain of these elements must be readable for good operation. Orifices@ control valves@ transmitters@ thermocouples@ level gages. and local controllers@ as well as analyzer sample points@ generally should be readily accessible from grade@ permanent platforms@ or fixed ladders. In this manual@ special consideration is given to the location@ accessibility@ and readability of the elements. Users of the various sections of this manual are reminded that in the rapidly advancing field of instrumentation no publication of this type can be complete@ nor can any written document be substituted for qualified engineering analysis. Certain systems are not covered herein because of their very specialized nature and limited use. When one of these systems gains general usage and installation reaches a fair degree of standardization@ this section will be revised to incorporate such additional information. Acknowledgment is made of the work of all the engineers and operating and maintenance personnel who@ through years of study@ observation@ invention@ and sometimes trial and error have contributed to the technology of mstrumentation. Suggested revisions are invited and should be submitted to the director of the Division of Refining@ American Petroleum Institute@ 1801 K Street@ N.W.@ Washington@ D. C. 20006.
